 Package : ceph Version : 14.2.21-1+deb11u1 CVE ID : CVE-2021-3979 CVE-2022-3650 CVE-2023-43040 CVE-2025-52555 Debian Bug : 1024932 1053690 1108410

 Ceph a distributed filesystem was affected by multiple vulnerabilties

 CVE-2021-3979

 A key length flaw was found in Ceph Storage component.
 An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

 CVE-2022-3650

 A privilege escalation flaw was found in Ceph. Ceph-crash.service allows a local attacker to escalate privileges to root in the form of a crash dump, and dump privileged information.

 CVE-2023-43040

 A flaw was found in Ceph RGW. An unprivileged user can write to any bucket(s) accessible by a given key if a POST's form-data contains a key called 'bucket' with a value matching the name of the bucket used to sign the request. The result of this is that a user could actually upload to any bucket accessible by the specified access key as long as the bucket in the POST policy matches the bucket in said POST form part.

 CVE-2025-52555

 An unprivileged user can escalate to root privileges in a ceph-fuse mounted CephFS by chmod 777 a directory owned by root to gain access. The result of this is that a user could read, write and execute to any directory owned by root as long as they chmod 777 it. This impacts confidentiality, integrity, and availability.

 For Debian 11 bullseye, these problems have been fixed in version 14.2.21-1+deb11u1.

 We recommend that you upgrade your ceph packages.
